In other developments in Buenoano`s murder trial in Orange Circuit Court Wednesday, her lawyer disclosed that part of her defense will be based the contention that her husband might have been poisoned accidentally by contact with the military herbicide Agent Blue or by chemicals used in citrus groves.

Officials of two companies that make embalming fluids also testified that the arsenic investigators found in Buenoano`s husband`s remains after his exhumation last year didn`t come from embalming fluids.

This morning, lawyers will lock horns over whether the prosecution can bring in evidence about the suspicious death of Buenoano`s common-law husband in Colorado several years ago, a death that she has not been charged with.

Buenoano is serving a life prison sentence for drowning her paraplegic son and trying to murder a boyfriend for insurance money.
